[0003] When manufacturing existing LED display screens, it is necessary to detect the completed LED display screens. Connect the LED display screen to the power supply and observe whether the LED display screen can be normally lit and detect whether the touch function of the LED display screen is normal.

[0016] As a preferred technical solution of the present invention: A fitting surface and a limiting surface are provided on the side of the limiting block close to the connecting platform. The fitting surface and the limiting surface are perpendicularly arranged.

[0017] The present invention has the following beneficial effects:

[0018] 1. The LED screen detection device drives the clamping arm to move through the detection robotic arm. By rotating the six axes of the detection robotic arm, the detection robotic arm can drive the clamping arm to directly clamp the screen body on the storage table and drive the screen body directly to the bottom of the capacitive stylus, enabling the capacitive stylus to detect the screen body. By directly clamping the screen body with the clamping arm, the process of detecting the screen body by the touch detection component and the image acquisition component can be directly carried out on the clamping arm, thus avoiding the steps in traditional devices of placing the screen body on a specific placement table and then detecting it through the touch detection component and the image acquisition component, improving the detection efficiency of the device.

[0019] 2. The LED screen detection device clamps the screen body with the clamping arm and outputs an image to the screen body during the process of driving the screen body to move by the detection robotic arm through the clamping arm, solving the problem that the wiring harness is detached from the LED display screen in the process of placing the LED display screen in a dedicated card slot in the traditional method.

[0020] 3. The LED screen detection device has the fitting surface and the limiting surface arranged perpendicularly. When the clamping seat drives the limiting block to clamp the screen body, the outer wall of the fitting surface fits with the side wall of the screen body, and the outer wall of the limiting surface fits with the vertical surface of the side wall of the screen body. Therefore, when the first telescopic device drives the sliding rod through the connecting plate and the sliding rod drives the limiting block to clamp the screen body through the clamping seat, it is only necessary to keep the fitting surface in contact with the side wall of the screen body. During the process of driving the screen body to move by the detection robotic arm through the clamping arm, the downward gravity of the screen body is applied to the limiting block through the limiting surface, and the limiting block rotates under the force, causing the fitting surface to squeeze the side wall of the screen body, thereby enabling the limiting block to maintain the clamping of the screen body, solving the problem in traditional clamping devices that applying too large a clamping pressure causes damage to the clamped object, and applying too small a clamping pressure causes the clamped object to fall.

[0043] In a preferred embodiment: The touch detection component 2 includes an installation platform 201. A sliding platform 202 is fixedly assembled on the top of the installation platform 201.

[0044] In a preferred embodiment: The touch detection component 2 is fixedly assembled to the top of the mounting table 1 through the mounting table 201. The inner wall of the first lead screw 203 is threadedly connected to the first sliding seat 204. The end of the first sliding table 202 is also fixedly assembled with a driving motor for driving the first lead screw 203. The inner wall of the second lead screw 206 is threadedly connected to the second sliding seat 208. The output end of the first driving motor 207 is fixedly assembled to the second lead screw 206.

[0045] In the above structure, the driving motor drives the first lead screw 203 to rotate. By using the sliding sleeve connection between the first sliding seat 204 and the first sliding table 202, and the threaded connection between the first sliding seat 204 and the first lead screw 203, the first sliding seat 204 moves along the first sliding table 202 to achieve X-axis movement.

[0046] And the first driving motor 207 drives the second lead screw 206 to rotate. By using the sliding sleeve connection between the second sliding seat 208 and the second sliding table 205, and the threaded connection between the second sliding seat 208 and the second lead screw 206, the second sliding seat 208 moves along the second sliding table 205 to achieve Y-axis movement.

[0047] When the detection robotic arm 4 drives the screen body 5 to move to the bottom of the capacitive touch pen 210, the touch detection component 2 can drive the capacitive touch pen 210 to achieve X and Y axis movement, and then the capacitive touch pen 210 performs touch screen detection on the screen body 5.

[0048] In a preferred embodiment: The image acquisition component 3 includes a second mounting table 301. The outer wall of the second mounting table 301 close to the detection robotic arm 4 is fixedly assembled with a third sliding table 302. The outer wall of the third sliding table 302 is slidably sleeved with a third sliding seat 305. The inner wall of the third sliding table 302 is rotatably connected to a third lead screw 304. The bottom of the third sliding table 302 is fixedly assembled with a second driving motor 303. The outer wall of the third sliding seat 305 is fixedly assembled with a camera 306.

[0049] The output shaft of the second driving motor 303 is fixedly assembled to the third sliding table 302. The inner walls of the third sliding table 302 and the third sliding seat 305 are threadedly connected.

[0050] In the above structure, the second driving motor 303 drives the third sliding table 302. By using the threaded connection between the third sliding seat 305 and the third sliding table 302, the third sliding seat 305 drives the camera 306 to move up and down. Then, when the detection robotic arm 4 drives the screen body 5 to move to the bottom of the camera 306, the camera 306 can adjust its focal length by moving up and down.

[0051] In a preferred embodiment: The detection robotic arm 4 includes a mounting plate 401. A turntable 402 is fixedly assembled at the top of the mounting plate 401. A first robotic arm 403 is rotatably connected to the top of the turntable 402. A second robotic arm 404 is rotatably connected to the top of the first robotic arm 403. A third robotic arm 405 is rotatably connected to the inner wall of the end of the second robotic arm 404 away from the first robotic arm 403. A fourth robotic arm 406 is rotatably connected to the end of the third robotic arm 405 away from the second robotic arm 404. A fifth robotic arm 407 is rotatably connected to the inner wall of the end of the fourth robotic arm 406 away from the third robotic arm 405. A clamping arm 408 is rotatably connected to the outer wall of the end of the fifth robotic arm 407 away from the fourth robotic arm 406.

[0052] In a preferred embodiment: The detection robotic arm 4 is fixedly assembled to the top of the workbench 1 through the mounting plate 401. Driving motors are embedded in the inner cavities of the turntable 402, the first robotic arm 403, the second robotic arm 404, the third robotic arm 405, the fourth robotic arm 406, and the fifth robotic arm 407. The turntable 402 rotates with the first robotic arm 403 through the operation of the driving motor. The first robotic arm 403 rotates with the second robotic arm 404 through the operation of the driving motor. The third robotic arm 405 rotates with the fourth robotic arm 406 through the operation of the driving motor. The third robotic arm 405 rotates with the fourth robotic arm 406 through the operation of the driving motor. The fourth robotic arm 406 rotates with the fifth robotic arm 407 through the operation of the driving motor. The fifth robotic arm 407 rotates with the clamping arm 408 through the operation of the driving motor.

[0053] In the above structure, the detection robotic arm 4 drives the clamping arm 408 to move. Through the six-axis rotation of the detection robotic arm 4, the detection robotic arm 4 can drive the clamping arm 408 to directly clamp the screen body 5 on the storage table and drive the screen body 5 to directly move to the bottom of the capacitive touch pen 210, realizing the detection of the screen body 5 by the capacitive touch pen 210. By directly clamping the screen body 5 with the clamping arm 408, the process of detecting the screen body 5 by the touch detection component 2 and the image acquisition component 3 can be directly carried out on the clamping arm 408, thus avoiding the steps of placing the screen body 5 on a specific placement table and then detecting it by the touch detection component 2 and the image acquisition component 3 in traditional equipment, and improving the detection efficiency of the equipment.

[0054] In a preferred embodiment: The plugging component includes a fixing plate 40810 and a sliding plate 40813. A driving motor three 40811 is fixedly assembled to the inner wall of the middle of the fixing plate 40810. A lead screw four 40812 is fixedly assembled to the output shaft of the driving motor three 40811. An expander two 40814 is fixedly assembled to one end of the sliding plate 40813. A plugging male seat 40815 is fixedly assembled to the telescopic end of the expander two 40814 close to the screen body 5.

[0055] The connecting plate 4087 and the end of the sliding rod 4085 are fixedly assembled. The fixing plate 40810 and a group of sliding rods 4085 are fixedly assembled. The sliding plate 40813 and a group of sliding rods 4085 are slidably sleeved. The lead screw four 40812 is threadedly connected to the inner wall of the sliding plate 40813. The connecting platform 4081 and the output shaft of the driving motor embedded in the inner cavity of the robotic arm five 407 are fixedly assembled.

[0056] By fixedly assembling the connecting platform 4081 and the output shaft of the driving motor embedded in the inner cavity of the robotic arm five 407, the clamping arm 408 can be driven to rotate through the driving motor embedded in the inner cavity of the robotic arm five 407;

[0057] By arranging the rubber adsorption seat 40816 on one side close to the screen body 5, connecting the rubber adsorption seat 40816 to the negative pressure machine, and controlling the size of the negative pressure output by the negative pressure machine to the rubber adsorption seat 40816 through the control device, the screen body 5 can achieve negative pressure adsorption through the rubber adsorption seat 40816;

[0058] The telescopic device one 4086 drives the sliding rod 4085 to move on the inner wall of the sliding groove 4084 through the connecting plate 4087, and further drives the two groups of sliding rods 4085 to drive the clamping seat 4088 to expand and contract;

[0059] The screen body 5 further includes a female socket 501 fixedly assembled with the screen body 5. When the female socket 501 is installed on the outer wall of the screen body 5 through the device, the installation position of the female socket 501 on the outer wall of the screen body 5 is fixed. At the same time, the length and width data of several screen bodies 5 in the same batch are consistent;

[0060] Therefore, by presetting the length and width data of the screen body 5 and the position data of the female socket 501 installed on the outer wall of the screen body 5 in the control device, when the telescopic device one 4086 detects the movement of the robotic arm 4, it drives the sliding rod 4085 through the connecting plate 4087, so that the two groups of sliding rods 4085 clamp the screen body 5 through the limit block 4089, cancel the negative pressure adsorption of the rubber adsorption seat 40816 on the screen body 5, and at the same time, the two groups of sliding rods 4085 move the screen body 5 left and right through the limit block 4089, so that the positions of the male socket 40815 and the female socket 501 correspond to each other, and the male socket 40815 is driven by the telescopic device two 40814 to be inserted into the female socket 501, so that the screen body 5 realizes data connection and further realizes picture display;

[0061] Drive the lead screw four 40812 to rotate through the drive motor three 40811. Utilize the threaded connection between the lead screw four 40812 and the sliding plate 40813, so that the sliding plate 40813 can move along the slide bar 4085 through the rotation of the drive motor three 40811. Furthermore, the sliding plate 40813 drives the plugging male seat 40815 to move through the telescopic device two 40814. By driving the screen body 5 to move simultaneously through the plugging male seat 40815 and the slide bar 4085, the plugging efficiency between the plugging male seat 40815 and the plugging female seat 501 can be further increased;

[0062] Clamp the screen body 5 through the two groups of slide bars 4085 by the limit blocks 4089, and cancel the negative pressure adsorption of the rubber adsorption seat 40816 on the screen body 5, which can reduce the time of using negative pressure by the rubber adsorption seat 40816, and then reduce the operation times of the negative pressure machine, thus achieving energy conservation;

[0063] The detection robotic arm 4 clamps the screen body 5 through the clamping arm 408, and after moving to the bottom of the capacitive stylus 210, the touch detection component 2 drives the capacitive stylus 210 to move in the X and Y axes. Furthermore, the capacitive stylus 210 performs a touch screen detection on the screen body 5. When the capacitive stylus 210 detects the screen body 5, the camera 306 detects and collects the real-time image of the screen body 5, and the collected data is matched in real time through the cloud, so as to obtain the detection result of the capacitive stylus 210 on the screen body 5;

[0064] Clamp the screen body 5 through the clamping arm 408, and output the image of the screen body 5 during the process that the detection robotic arm 4 drives the screen body 5 to move through the clamping arm 408. This optimizes the steps in the traditional device where the screen body 5 needs to be placed on a specific placement table and then detected by the touch detection component 2 and the image acquisition component 3, improving the detection efficiency of the device.

[0065] In a preferred embodiment: A fitting surface 40891 and a limiting surface 40892 are provided on the side of the limit block 4089 close to the connection table 4081, and the fitting surface 40891 and the limiting surface 40892 are perpendicularly arranged.

[0066] In the above structure, since the fitting surface 40891 and the limiting surface 40892 are perpendicularly arranged, when the card seat 4088 drives the limiting block 4089 to clamp the screen body 5, the outer wall of the fitting surface 40891 is in contact with the side wall of the screen body 5, and the outer wall of the limiting surface 40892 is in contact with the vertical plane of the side wall of the screen body 5. Therefore, when the first telescopic device 4086 drives the sliding rod 4085 through the connecting plate 4087, and the sliding rod 4085 drives the limiting block 4089 through the card seat 4088 to clamp the screen body 5, it is only necessary for the fitting surface 40891 to remain in contact with the side wall of the screen body 5. During the process that the detection robotic arm 4 drives the screen body 5 to move through the clamping arm 408, the downward gravity of the screen body 5 is applied to the limiting block 4089 through the limiting surface 40892, and the limiting block 4089 rotates under the force, so that the fitting surface 40891 squeezes the side wall of the screen body 5, thereby enabling the limiting block 4089 to maintain the clamping of the screen body 5.

[0067] Working principle: The detection robotic arm 4 drives the clamping arm 408 to move. Through the six-axis rotation of the detection robotic arm 4, the detection robotic arm 4 can drive the clamping arm 408 to directly clamp the screen body 5 on the storage table and drive the screen body 5 to directly move to the bottom of the capacitive touch pen 210, realizing the detection of the screen body 5 by the capacitive touch pen 210. By directly clamping the screen body 5 with the clamping arm 408, the process of detecting the screen body 5 by the touch detection component 2 and the image acquisition component 3 can be directly carried out on the clamping arm 408;

[0068] Specifically, by presetting the length and width data of the screen body 5 and the position data of the female socket 501 installed on the outer wall of the screen body 5 in the control device, the screen body 5 realizes negative pressure adsorption through the rubber adsorption seat 40816;

[0069] During the movement of the detection robotic arm 4, the first telescopic device 4086 drives the sliding rod 4085 through the connecting plate 4087, so that the two sliding rods 4085 clamp the screen body 5 through the limiting block 4089, cancel the negative pressure adsorption of the rubber adsorption seat 40816 on the screen body 5, and at the same time, the two sliding rods 4085 move the screen body 5 left and right through the limiting block 4089, thereby making the positions of the male socket 40815 and the female socket 501 correspond to each other, and driving the male socket 40815 to be inserted into the female socket 501 through the second telescopic device 40814, so that the screen body 5 realizes data connection and then realizes picture display;

[0070] After the detection robotic arm 4 clamps through the screen body 5 of the clamping arm 408 and moves to the bottom of the capacitive stylus 210, the touch detection component 2 drives the capacitive stylus 210 to move in the X and Y axes, so that the capacitive stylus 210 performs touch screen detection on the screen body 5. When the capacitive stylus 210 detects the screen body 5, the camera 306 detects and collects the real-time picture of the screen body 5, and the data collected is matched in real time through the cloud, so as to obtain the detection result of the capacitive stylus 210 on the screen body 5;

[0071] Since the fitting surface 40891 and the limiting surface 40892 are vertically arranged, when the card seat 4088 drives the limiting block 4089 to clamp the screen body 5, the outer wall of the fitting surface 40891 is attached to the side wall of the screen body 5, and the outer wall of the limiting surface 40892 is attached to the vertical surface of the side wall of the screen body 5. Therefore, when the first telescopic device 4086 drives the sliding rod 4085 through the connecting plate 4087 and the sliding rod 4085 drives the limiting block 4089 through the card seat 4088 to clamp the screen body 5, it is only necessary for the fitting surface 40891 to remain attached to the side wall of the screen body 5. During the process of the detection robotic arm 4 driving the screen body 5 to move through the clamping arm 408, the downward gravity of the screen body 5 is applied to the limiting block 4089 through the limiting surface 40892, and the limiting block 4089 rotates under the force, so that the fitting surface 40891 presses the side wall of the screen body 5, thereby enabling the limiting block 4089 to maintain the clamping of the screen body 5.
